Improving appropriateness of acid-suppressive medication use via computerized clinical decision support.

As part of the Choosing Wisely Campaign, the Society of Hospital Medicine identified reducing inappropriate use of acid-suppressive medication for stress ulcer prophylaxis as 1 of 5 key opportunities to improve the value of care for hospitalized patients. We designed a computerized clinical decision support intervention to reduce use of acid-suppressive medication for stress ulcer prophylaxis in hospitalized patients outside of the intensive care unit at an academic medical center. Using quasiexperimental interrupted time series analysis, we found that the decision support intervention resulted in a significant reduction in use of acid-suppressive medication with stress ulcer prophylaxis selected as the only indication, a nonsignificant reduction in overall use, and no change in use on discharge.

Preventing potentially inappropriate medication use in hospitalized older patients with a computerized provider order entry warning system.

Background: Potentially inappropriate medication (PIM) use in hospitalized older patients is common. Our objective was to determine whether a computerized provider order entry (CPOE) drug warning system can decrease orders for PIMs in hospitalized older patients.

Methods: We used a prospective before-and-after design among patients 65 years or older admitted to a large, urban academic medical center in Boston, Massachusetts, from June 1, 2004, through November 29, 2004 (for patients admitted before the warning system was added), and from March 17, 2005, through August 30, 2008 (patients admitted after the warning system was added).
